DIA [1.3K]

Answer:

Explanation:

Thermal conductivity of glass pane = .8 W / m K

For conduction of heat , the formula is as follows

Q = \frac{kA(T_1 - T_2 )t}{d }   ; Q is heat conducted in time t by a medium of thickness d , area of cross section A and ( T₁ - T₂ ) is the temperature difference .

Putting the values in the equation

Q = \frac{.8 \times32\times(25 - 0 )\times1}{.0062 }

= 103225.8 W

b )

energy lost in one day

= 103225.8 x 24 x 60 x 60

= .89187 x 10¹⁰ J .

Why do solids have a definite shape?
ddd [48]
Any matter that is a solid<span> has a </span>definite shape<span> and a </span>definite<span> volume. The molecules in a </span>solid<span> are in fixed positions and are close together. Although the molecules can still vibrate, they cannot move from one part of the </span>solid<span> to another part. As a result, a </span>solid does<span> not easily change its </span>shape<span> or its volume</span>

The speed that a tsunami can travel is modeled by the equation , where s is the speed in kilometers per hour and d is the averag
CaHeK987 [17]

The speed of tsunami is a.0.32 km. 

Steps involved  :

The equation s = 356d models the maximum speed that a tsunami can move at. It reads as follows: s = 200 km/h d =?

Let's now change s to s in the equation to determine d: s = 356√d 200 = 356√d √d = 200 ÷ 356 √d = 0.562 Let's square the equation now by squaring both sides: (√d)² = (0.562) ² d = (0.562)² = 0.316 ≈ 0.32

As a result, 0.32 km is roughly the depth (d) of water for a tsunami moving at 200 km/h.
